I havent fully understood the whole concept of the mmo world map. If you're able to fight battles far outside your own borders. How will the environment in the tons of different areas be like? Lets say you send out an army to explore, and you met up with another army, and you have to fight them, will a battlemap be loaded by then? Will the battlefields terrain and environment be same as it should be on the world map? Will it be random how the map looks like in that area, for example, if you fight first time in that area its a large forest area with a lake in a valley in middle, second time in the exact same place, will it look the same as it did the first time, or will it be randomised how it looks like?

Sorry if its hard to understand the question, i dont know how else to put it.
